is PetitParser eager by default?
by Peter Uhnak Jan. 21, 2017

Jan. 21, 2017

Is PetitParser eager by default? I've used PetitParser countless times so I am really baffled why this doesn't work str := 'a0b'. #any asParser star, #digit asParser, #any asParser star parse: str. -> PPFailure (input expected at: 3) Thanks, Peter

Google visibility?
by Siemen Baader Jan. 21, 2017

Jan. 21, 2017

Has anybody looked into SEO'ing any of the great documentation and archived questions on the mailing list? It strikes me that I often can't find the answer to questions I have on Google, but they are often answered in material that I can find when I look manually for some time or am pointed at it by an experienced member of the community. I also miss Pharo - content on Stackoverflow, it is a very efficient way to get past road blocks quickly. Any thoughts or history to bring me up to speed with? cheers, Siemen

Couple grafoscopio notes
by Peter Uhnak Jan. 21, 2017

Jan. 21, 2017

Hi, I've started playing around with grafoscopio, I am happy that I can finally organize all those little scripts and not lose them all the time. :) However there are couple of issues and notes I've ran into (don't worry about fixing them in any timely fashion, it is not blocking me) 1. For saving `UITheme builder` is used, but the correct approach is via `UIManager default` * this has obvious impact if the UIManager is different (UIManager has reference to UITheme, but not the other way around) To see all the calls, you can do this (or find the uses manually) calls := UITheme allCallsOn select: [ :each | each package name = #Grafoscopio ]. SystemNavigation default browseMessageList: calls name: 'Users of class UITheme' autoSelect: 'UITheme builder'. 2. Typo "Add nodo" -> "Add node" 3. "Move up|down node" -> "Move node up|down" (to be consistend with the rest of the naming) 4. During installation (from Catalog) a 'Grafoscopio' folder is created in documents and documentation is downloaded This is a big no. Please don't do this. Not only it violates the isolation of images, but it actually breaks the installation itself when you install Grafoscopio in two different images. If you have to download the docs and you cannot just store them inside the image (which would be logical choice for read-only), then please use the image's directory by default, and only in e.g. development mode use some other location. 5. Node-related bugs Imho this is somehow related to improper use and updates of tree. I remember I had similar issues some time ago, so maybe I can take a look at this in couple of weeks. These bugs sometimes autoresolve themselves (so sometimes it is usable and sometimes not) * 1. Launch > new notebook * 2. Add node > error * 1. Launch > new notebook * 2. Select Node 1 * 3. Add node * 4. Select newNode * 5. rename node to something else * 6. Click on previous "Node 1" > error To summarize: Most are just minor things or annoyances, but #4 is breaking --- as I have to remember to delete the folder every time I want to download Grafoscopio in new image. (If it works for you, then maybe it's platform related (I tested this on Windows 10); in either case, the data related to the image should stay with the image (either in the image, or in the image's folder), and not somewhere in the system). Thanks! Peter

Help required in refreshing MenuModel
by Jigyasa Grover Jan. 20, 2017

Jan. 20, 2017

Hi I have been building a Pharo UI using Spec. I utilized *MenuModel* for building a *menu*, and now I want to refresh the *menu*after an item in it has been clicked. For example: I click *option1* in *menu* and some other item (say *option2*) in *menu* changes to *option3*. I hope my question is clear. I tried: -- /menu autoRefresh: true./ I was planning to use the /initializePresenter/ method, but am stuck currently. Help appreciated.

Moreover, due to the portability, mobility and increasingly evolutionary nature of software systems, such adaptations should be enacted even while the system is running. Developing such software systems can prove challenging, and many seemingly different techniques to address this concern have been proposed over the last couple of years. The intention of the LASSY workshop is to congregate all topics relevant to dynamic adaptation and run-time evolution of software systems, ranging from a computer science perspective covering the domains of programming languages, model-driven software development, software and service composition, context-aware databases, software variability, requirements engineering, UI adaptation and other domains, to a human perspective covering sociological or ethical implications of dynamic software systems. The workshop provides a space for discussion and collaboration between researchers working on the problem of enabling live adaptations to software systems, across the development stack. Topics of Interest: * Design and Implementation of Live Adaptive Software Systems * Context-, aspect-, feature-, role- and agent-oriented programming * Context representation and discovery * Context-aware model-driven software development * Context-aware data management * Software variability and dynamic product lines * Self-adaptive, self-explanatory systems * Inconsistency management, verification, and validation * Middleware and Runtime of Live Adaptive Software Systems * Dynamic software evolution, upgrades and configuration * Dynamic software and service composition mechanisms * Dynamic software architecture and middleware approaches * Dynamic user interface adaptation and multimodal user interfaces * Impact and Assessment of Live Adaptive Software Systems * User acceptance and usability issues * Human, sociological, ethical and legal aspects * Privacy and security aspects of dynamic adaptability * Live adaptation in smart environments (e.g. smart rooms, smart robot cells, smart factories, smart cities) * Self-adaptation and emergence in SoS and CPSoS ********************************************************************** MiniPLoP 2017 - Mini Pattern Languages of Programs writers' workshop Workshop date: Mon 3 Apr 2017 http://2017.programming-conference.org/track/MiniPLoP-2017-papers ********************************************************************** Software developers and those involved with programming have long observed that certain patterns recur and endure across different applications and systems. The growing interest in Design Patterns, Architectural Patterns, Analysis Patterns, Pedagogical Patterns, Agile Patterns, and so on, represents an effort to catalog and better communicate knowledge, providing handbooks of proven solutions to common problems. The MiniPLoP writers' workshop brings together researchers, educators, and practitioners whose interests span a remarkably broad range of topics and who share an interest in exploring the power of the pattern form. MiniPLoP invites you to add your expertise to the growing corpus of patterns. MiniPLoP focuses on improving the expression of patterns. You will have the opportunity to refine and extend your patterns or pattern ideas with the help from knowledgeable and sympathetic fellow pattern enthusiasts. You will also be able to discuss applications of patterns in industry and academia. Techniques for Pattern Mining will also be presented. Highlights include group discussions on patterns, an introduction to pattern writing, an international keynote, and the writersâ workshop. This MiniPLoP at <Programming> 2017 has the goal to help beginners learn more about the pattern community. If you have some patterns or pattern ideas you would like to have brainstormed or workshopped, please contact the organizers at: miniplop2017(a)hillside.net **************************************************************** MOMO 2017 - 2nd Workshop on Modularity in Modelling Abstract submissions (optional) **extended** : Sun Feb 5 2017 Paper submissions **extended** : Sun Feb 12 2017 Notifications: Wed Feb 22 2017 Workshop date: Mon 3 Apr 2017 http://www.momo2017.ece.mcgill.ca/cfp.htm **************************************************************** Extending the time-honored practice of separation of concerns, Model-Driven Engineering (MDE) promotes the use of separate models to address the various concerns in the development of complex software-intensive systems. The main objective is to choose the right level of abstraction to modularize a concern, specify its properties and reason about the system under development depending on stakeholder and development needs. While some of these models can be defined with a single modelling language, a variety of heterogeneous models and languages are typically used in the various phases of software development. Furthermore, Domain-Specific Modelling Languages designed to address particular concerns are also increasingly used. Despite the power of abstraction of modelling, models of real-world problems and systems quickly grow to such an extent that managing the complexity by using proper modularization techniques becomes necessary. As a result, many (standard) modelling notations have been extended with aspect-oriented mechanisms and advanced composition operators to support advanced separation of concerns, to combine (possibly heterogeneous) models modularizing different concerns, to execute an application based on modularized models, and to reason over global properties of modularized models. The Second International Modularity in Modelling Workshop brings together researchers and practitioners interested in the theoretical and practical challenges resulting from applying modularity, advanced separation of concerns, and advanced composition at the modelling level. It is intended to provide a forum for presenting new ideas and discussing the impact of the use of modularization in the context of MDE at different levels of abstraction. We are interested in submissions on all topics related to modularity and modelling including but not limited to: * Modularization Support in Modelling Languages and Tools * Model Interfaces * Homogeneous Model Composition Operators * Heterogeneous Model Composition Operators * Visualization of Modularized and Composed Models * Effects of Using Modularization and Composition in Modelling * On Verification and Validation * On Reuse * On the Model-Driven Software Development Process (Requirements Engineering, Software Architecture, Software Design, Implementation) * On Maintenance * Experience Reports / Empirical Evaluations of Applying Modularization and Composition in Modelling * Feature-Oriented, Aspect-Oriented and Concern-Oriented Modelling * Modularization support and composition operators for specific modelling notations * Modelling essential characteristics of specific (crosscutting) concerns * Multi-View Modelling: avoiding inconsistencies, avoiding Redundancies * Support for Detecting and/or Resolution of Feature Interactions * Domain-Specific Modelling * Modularization for Domain-Specific Languages * Composition for Domain-Specific Languages * Domain-specific Aspect Models ****************************************************************************** MoreVMs 2017 - 1st Workshop on Modern Language Runtimes, Ecosystems, and VMs Submissions: Wed 15 Feb 2017 Notifications: Wed 1 Mar 2017 Workshop date: Mon 3 Apr 2017 http://2017.programming-conference.org/track/MoreVMs-2017-papers ****************************************************************************** The main goal of the workshop is to bring together both researchers and practitioners and facilitate effective sharing of their respective experiences and ideas on how languages and runtimes are utilized and where they need to improve further. We welcome presentation proposals in the form of extended abstracts discussing experiences, work-in-progress, as well as future visions from the academic as well as industrial perspective. Relevant topics include, but are definitely not limited to, the following: * Extensible VM design (compiler- or interpreter-based VMs) * Reusable runtime components (e.g. interpreters, garbage collectors, intermediate representations) * Static and dynamic compiler techniques * Techniques for compilation to high-level languages such as JavaScript * Runtimes and mechanisms for interoperability between languages * Tooling support (e.g. debugging, profiling, etc.) * Programming language development environments and virtual machines * Case studies of existing language implementations, virtual machines, and runtime components (e.g. design choices, tradeoffs, etc.) * Language implementation challenges and trade-offs (e.g. performance, completeness, etc.) * Surveys and applications usage reports to understand runtime usage in the wild * Surveys on frameworks and their impact on runtime usage * New research ideas on how we want to build languages in the future ************************************************************************** PASS 2017 - 1st Workshop on Programming Across the System Stack Submissions: Mon 13 Feb 2017 Notifications: Mon 27 Feb 2017 Workshop date: Tue 4 Apr 2017 http://2017.programming-conference.org/track/PASS-2017#Call-for-Papers ************************************************************************** The landscape of computation platforms has changed dramatically in recent years. Emerging systems - such as wearable devices, smartphones, unmanned aerial vehicles, Internet of things, cloud computing servers, heterogeneous clusters, and data centers - pose a distinct set of system-oriented challenges ranging from data throughput, energy efficiency, security, real-time guarantees, to high performance. In the meantime, code quality, such as modularity or extensibility, remains a cornerstone in modern software engineering, bringing in crucial benefits such as modular reasoning, program understanding, and collaborative software development. Current methodologies and software development technologies should be revised in order to produce software to meet system-oriented goals, while preserving high internal code quality. The role of the Software Engineer is essential, having to be aware of the implications that each design, architecture and implementation decision has on the application system ecosystem. This workshop is driven by one fundamental question: How does internal code quality interact with system-oriented goals? We welcome both positive and negative responses to this question. An example of the former would be modular reasoning systems specifically designed to promote system-oriented goals, whereas an example of the latter would be anti-patterns against system-oriented goals during software development. Areas of interest include but are not limited to: * Energy-aware software engineering (e.g. energy efficiency models, energy efficiency as a quality attribute) * Modularity support (e.g., programming language design, development tools or verification) for applications in resource-constrained or real-time systems * Emerging platforms (e.g., Internet of Things and wearable devices) * Security support (e.g., compositional information flow, compositional program analysis) * Software architecture for reusability and adaptability in systems and their interactions with applications * Empirical studies (patterns and anti-patterns) on the relationship between internal code quality and system-oriented goals * Software engineering techniques to balance the trade-off between internal code quality and efficiency * Memory bloats and long-tail performance problems across modular boundaries * Program optimization across modular boundaries * Internal code quality in systems software * Reasoning across applications, compilers, and virtual machines **************************************************************** PX 2017 - 2nd Programming Experience Workshop Submissions: Sat 4 Feb 2017 Notifications: Mon 27 Feb 2017 Workshop date: Mon 3 Apr 2017 http://programming-experience.org/px17 **************************************************************** Imagine a software development task: some sort of requirements and specification including performance goals and perhaps a platform and programming language. A group of developers head into a vast workroom. In that room they discover they need to explore the domain and the nature of potential solutionsâthey need exploratory programming. The Programming Experience Workshop is about what happens in that room when one or a couple of programmers sit down in front of computers and produce code, especially when itâs exploratory programming. Do they create text that is transformed into running behavior (the old way), or do they operate on behavior directly (âlivenessâ); are they exploring the live domain to understand the true nature of the requirements; are they like authors creating new worlds; does visualization matter; is the experience immediate, immersive, vivid and continuous; do fluency, literacy, and learning matter; do they build tools, meta-tools; are they creating languages to express new concepts quickly and easily; and curiously, is joy relevant to the experience? Correctness, performance, standard tools, foundations, and text-as-program are important traditional research areas, but the experience of programming and how to improve and evolve it are the focus of this workshop, and in this edition we would like to focus on exploratory programming. The technical topics include: * Exploratory programming * Live programming * Authoring * Representation of active content * Visualization * Navigation * Modularity mechanisms * Immediacy * Literacy * Fluency * Learning * Tool building * Language engineering ************************************************************************* ProWeb 2017 - 1st Workshop on Programming Technology for the Future Web Submissions: Wed 15 Feb 2017 Notifications: Wed 1 Mar 2017 Workshop date: Tue 4 Apr 2017 http://2017.programming-conference.org/track/proweb-2017-papers ************************************************************************* Full-fledged web applications have become ubiquitous on desktop and mobile devices alike. Whereas âresponsiveâ web applications already offered a more desktop-like experience, there is an increasing demand for ârichâ web applications (RIAs) that offer collaborative and even off-line functionality âGoogle docs being the prototypical example. Long gone are the days that web servers merely had to answer incoming HTTP request with a block of static HTML. Todayâs servers react to a continuous stream of events coming from JavaScript applications that have been pushed to clients. As a result, application logic and data is increasingly distributed. Traditional dichotomies such as âclient vs. serverâ and âoffline vs. onlineâ are fading. The 1st International Workshop on Programming Technology for the Future Web, or ProWeb17, is a forum for researchers and practitioners to share and discuss new technology for programming these and future evolutions of the web. We welcome submissions introducing programming technology (i.e., frameworks, libraries, programming languages, program analyses and development tools) for implementing web applications and for maintaining their quality over time, as well as experience reports about the use of state-of-the-art programming technology. Relevant topics include, but are not limited to: * Quality on the new web: static and dynamic program analyses; code, design test and process metrics; development and migration tools; automated testing and test generation; contract systems, type systems, and web service API conformance checking; â¦ * Hosting languages on the web: new runtimes; transpilation or compilation to JavaScript, WebAssembly, asm.js, â¦ * Designing languages for the web: multi-tier (or tierless) programming; reactive programming; frameworks for multi-tier or reactive programming on the web; â¦ * Distributed data sharing, replication and consistency: cloud types, CRDTs, eventual consistency, offline storage, peer-to-peer communication, â¦ * Security on the web: client-side and server-side security policies; policy enforcement; proxies and membranes; vulnerability detection; dynamic patching, â¦ * Surveys and case studies using state-of-the-art web technology (e.g., WebAssembly, WebSocket, LocalStorage, AppCache, ServiceWorkers, Meteor, deepstream.io, Angular.js, React and React Native, Swarm.js, Caja, TypeScript, Proxies, ClojureScript, Amber Smalltalk, Scala.js, â¦) * Ideas on and experience reports about: how to reconcile the need for quality with the need for agility on the web; how to master and combine the myriad of tier-specific technologies required to develop a web application, â¦ * Position statements on what the future of the web will look like **************************************************************** Salon des RefusÃ©s 2017 Submissions: Wed 1 Feb 2017 Notifications: Fri 17 Feb 2017 Workshop date: Tue 4 Apr 2017 https://refuses.github.io **************************************************************** Salon des RefusÃ©s (âexhibition of rejectsâ) was an 1863 exhibition of artworks rejected from the official Paris Salon. The jury of Paris Salon required near-photographic realism and classified works according to a strict genre hierarchy. Paintings by many, later famous, modernists such as Ãdouard Manet were rejected and appeared in what became known as the Salon des RefusÃ©s. This workshop aims to be the programming language research equivalent of Salon des RefusÃ©s. We provide a venue for exploring new ideas and new ways of doing computer science. Many interesting ideas about programming might struggle to find space in the modern programming language research community, often because they are difficult to evaluate using established evaluation methods (be it proofs, measurements or controlled user studies). As a result, new ideas are often seen as âunscientificâ. This workshop provides a venue where such interesting and thought-provoking ideas can be exposed to critical evaluation. Submissions that provoke interesting discussion among the program committee members will be published together with an attributed review that presents an alternative position, develops additional context or summarizes discussion from the workshop. This means of engaging with papers not just enables explorations of novel programming ideas, but also encourages new ways of doing computer science. Topics of interest The scope of the workshop is determined more by the format of submissions than by the specific area of programming language or computer science research that we are interested in. We welcome submissions in a format that makes it possible to think about programming in a new way, including, but not limited to: * Thought experiments â we believe that thought experiments, analogies and illustrative metaphors can provide novel insights and inspire fruitful programming language ideas. * Experimentation â we find prejudices in favour of theory, as far back as there is institutionalized science, but programming can often be seen more as experimentation than as theorizing. We welcome interesting experiments even if there is yet no overarching theory that explains why they happened. * Paradigms â all scientific work is rooted in a scientific paradigm that frame what questions can be asked. We encourage submissions that reflect on existing paradigms or explore alternative scientific paradigms. * Metaphors, myths and analogies â any description of formal, mathematical, quantitative or even poetical nature still represents just an analogy. We believe that fruitful ideas can be learned from less common forms of analogies as well as from the predominant, formal and mathematical ones. * From jokes to science fiction â a story or an artistic performance may explore ideas and spark conversations that provide crucial inspiration for development of new computer science thinking.

Usability issue with Pharo 5
by Hilaire Jan. 20, 2017

Jan. 20, 2017

Playing with Pharo5 with Phratch, I just noted two usability problems: - Short cut for class ref does not work (CTRL+SHIFT+B) - selecting a word by double clicking in text editor is not as good as before, you need to be fast on your double click. It worked as a charm with Pharo 3. - when right clicking on a class name, you may lose the source code view on the bottom, it is a 1/2 event It is depressing to see these usability regressions release after release... -- Dr. Geo http://drgeo.eu -- Dr. Geo http://drgeo.eu
